UNITED STATES PATENT OFFICE.

BENJAMIN F. GREENE, OF PITTSBURG, PENNSYLVANIA.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 410,668, dated September 10, 1889.

Application filed June 15, 1889. Serial No. 314,371. (No model.)

To all wh0m it may concern:

Be it known that I, BENJAMIN F. GREENE, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Stoppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of bottlestoppers known as swing-stopper.

The object of my invention is to provide a double lock and a metallic cap-piece which will protect the rubber stopper and guide it to the mouth of the bottle in a more perfect manner.

\Vith these ends in view my invention consists in the peculiar features and combinations of parts more fully described hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my invention, in which the stopper is shown closed; Fig. 2, a similar view showing the stopper open and thrown back against the bottle; Figs. 3 and 5, detail views of the cap-piece; and Fig. 4, a modified form of the cap-piece, in which a rubber mold n is employed instead of the rubber disk.

The reference-letter (t represents the locking-lever, which is provided with inwardlybent arms I), having trunnions c fitting within the eyes (1, formed in the neck-band c. It will be observed that the arm I) is bent slightly out of alignment with the handle portion a of the locking-lever, in order to throw the bearing 0d the center in an eccentric manner to perfect the locking operation.

lhe yoke f is provided with eyes at its lower extremity, by means of which it is attached to the lever a at the bend or pivotal point 9.

The cap-piece It consists of a metal plate 1', oval in general outline, as seen in Fig. 3. Its opposite ends are provided with ears j, having elongated perforations 2, through which the yoke f passes, as will be more clearly seen in Fig. 5. This gives the cap h a fixed position on the yoke-bail, with an oscillating movement sufiicient to allow the cap with the elastic stopper an easy entrance to the mouth of the bottle, and so permit the yokebail to move only far enough in the combination cap-piece to look over the center securely. The ends j are also slightly bent downward, in order to leave no abrupt projections upon the exterior.

A button Zis secured to the plate, and its base is provided with a rivet or disk m upon the outside of the plate, which disk comes in contact with the under part of the bail where it passes over the top of the cap-piece. The base of the button also extends below the under surface of the cap-piece to form a shoulder 2".

A rubber disk at surrounds the shank 0 of the button, and can be detached and put on in the well-known way.

In operating my device, when the bottle is closed, the locking-lever a is pulled back, which operation throws the pivotal point g off the center and allows the lever to be drawn down upon the neck of the bottle, as in Fig. 2, and when in this position the cap-piece will fall or swing forward and allow the contents of the bottle to be emptied.

In the closing operation the cap-piece is raised up until it comes over the mouth of the bottle. The lever a is then elevated to the position shown in Fig. 1, which looks and holds the cap-piece firmly in place.

It will be observed that in the opening and closing operation the cap-piece does not swing or have pivotal movement upon the yoke, and hence there are but two pivotal points on which the parts operate relatively to each other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a bottle-stopper, a locking-lever provided with inwardly-bent arms upon its lower ends, said arms terminating in trunnions and being bent upwardly and out of alignment with the main portion of the lever, in combination with a yoke provided with eyes upon its lower ends, through which the lever passes at the bend g, a cap-plate provided with perforations upon opposite sides, through which the yoke passes and an elastic stopperdisk, all arranged and adapted to operate substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

BENJAMIN F. GREENE.
